ELECTRICAL HEATERS
The heating element is made of tubular finned sheath coil of the highest grade resistance wire precisely centered in a 1/2"
dia. Copper plated steel sheath and insulated from the sheath by magnesium oxide powder. Through the application of
mechanical force, the powder is packed to a rock like density, insuring rapid heat dissipation from the resistance coil to the
sheath section at each end of the element is unheated to remove source of heat from the terminals. The surface area
exposed to the air is increased by the application of 1-1/4" OD fins. The fin is made of steel wound around the element in
a continuous spiral which makes five turns per linear inch of element. The sheath and fin are permanently bonded together
by copper brazing.
